@wuast94 Which version of FOG do you use? Haven’t done it myself in Docker, so I am just searching the web and forums and found this: https://wiki.fogproject.org/wiki/index.php/Install_FOG_in_a_Docker_Container
Sounds like you need to make sure NFS is loaded on the system hosting the Docker container! modprobe nfs && modprobe nfsd
Someone started one on docker.com but never kept it up to date: https://hub.docker.com/u/fogproject and https://hub.docker.com/r/lspiehler/fogproject/
And you can find various more sources :https://github.com/RustyBower/docker-fog
